Have a Lumia Icon with 8.1 Preview? Hold off on that Treasure Tag purchase until Cyan

File this under beware early adopters, but in case you havent heard, Verizon has started selling the $29.99 Nokia Treasure Tag accessory. Pairing via NFC and Bluetooth, the little gizmo allows you to track via HERE Maps whatever possession you attach it to, making it perfect for your keys or new baby (I jest).
Unfortunately, if you buy one today like I did then youll find yourself with a useless purchase if youre on Windows Phone 8.1 Preview for Developers. Thats because it says you need Lumia Cyan for it to work. As a reminder, Lumia Cyan is the forthcoming firmware update that will roll out with Windows Phone 8.1 in the coming weeks and months.
